I've been thinking about this as well. While I too have way too much stuff, I always assume that much of my collection will be in storage and only a portion can be displayed. For the new films, I will buy either highly articulated or 5POA 3 3/4 figures. I like them both. What concerns me is that Disney/Lucasfilm/Hasbro are only going to make top shelf characters. And with a new movie out every year, it will give them little time for the background characters and cool aliens. What's kept me interested in SW figures is the depth of the character selection.
I'm always up for a good vehicle too, but if the release the OTC Falcon with a new radar dish (Because Lando broke the last one) I'll have to pass.
